reviewboard.diffviewer.opcode_generator¶

class MoveRange(start, end, groups=[])[source]¶

Bases: object

Stores information on a move range.

This will store the start and end of the range, and all groups that are a part of it.

__init__(start, end, groups=[])[source]¶

property last_group[source]¶

add_group(group, group_index)[source]¶

__repr__()[source]¶

Return repr(self).

class DiffOpcodeGenerator(differ, diff=None, interdiff=None, request=None, **kwargs)[source]¶

Bases: object

ALPHANUM_RE = re.compile('\\w')[source]¶

WHITESPACE_RE = re.compile('\\s')[source]¶

MOVE_PREFERRED_MIN_LINES = 2[source]¶

MOVE_MIN_LINE_LENGTH = 20[source]¶

TAB_SIZE = 8[source]¶

__init__(differ, diff=None, interdiff=None, request=None, **kwargs)[source]¶

Initialize the opcode generator.

Changed in version 3.0.18: Added the request and **kwargs parameters.

Parameters:

• differ (reviewboard.diffviewer.differ.Differ) – The differ being used to generate the diff.

• diff (bytes, optional) – The raw contents for the diff.

• interdiff (bytes, optional) – The raw contents for the diff on the other end of an interdiff range, if generating an interdiff.

• request (django.http.HttpRequest) – The HTTP request from the client.

• **kwargs (dict) – Additional keyword arguments, for future expansion.

__iter__()[source]¶

Returns opcodes from the differ with extra metadata.

This is a wrapper around a differ’s get_opcodes function, which returns extra metadata along with each range. That metadata includes information on moved blocks of code and whitespace-only lines.

This returns a list of opcodes as tuples in the form of (tag, i1, i2, j1, j2, meta).

get_diff_opcode_generator_class()[source]¶

Returns the DiffOpcodeGenerator class used for generating opcodes.

set_diff_opcode_generator_class(renderer)[source]¶

Sets the DiffOpcodeGenerator class used for generating opcodes.

get_diff_opcode_generator(*args, **kwargs)[source]¶

Returns a DiffOpcodeGenerator instance used for generating opcodes.
